Part-ST Submissions

Part ST Submissions

Note that Part ST Submissions is undergoing further refinements. More updates will be released in future COP versions.

 

  • Under the new Regulatory Approval for Building Works, project teams are required to collaborate and submit a set of coordinated models. Requirements imposed at each gateway are often major requirements that have cross agencies’ dependencies.
  • Agency specific requirements may be submitted as independent submissions subsequently. Some examples of structural submissions that can be submitted as an independent submission includes:
    • Structural submissions for ancillary works (eg: cladding, barrier)
    • Structural submissions for temporary works (eg: ERSS)
  • Industry has raised concerns that while overall design can be done upfront, detailed structural calculations and AC/ACO reports take time to develop. Projects may face significant delay in commencement of works if everything must be submitted and cleared before the relevant approval and permit can be issued.
  • To address these concerns, detailed structural design and calculations of eligible projects need not be submitted in a single attempt but done through a limited number of part ST submissions

 


  • Building projects (non-infrastructure projects):
  1. Any project with a Gross Floor Area (GFA) > 40,000sqm is eligible for part ST submission if –

a. .the project consists of 5 or more blocks of building of at least 4 storeys high each; or

b. the project consists of 3 or more blocks of building of at least 4 storeys high each, with common podium or basement.

 

  • Infrastructure works
  1. Infrastructure works that function like a building with length > 150m  
    (e.g. MRT stations, transport nodes/ interchanges);
  2. Infrastructure works that are mostly engineering works with length > 400m
    (e.g. viaducts, large scale drains, sewers)
  3. Infrastructure works that are mostly coastal works with length > 4,000m
    (e.g. land reclamation, revetment, sea wall, bund wall)

Scope/Scale of Works Number of Packages Allowed
Superstructure 1 no. of Part ST Submission for every 4 blocks
•E.g. consisting of 9 blocks
•Split into 3 no.s of Part ST Submissions of equal size (as far as possible): GFA for each of the submissions should cover about 1/3 of the total GFA of these blocks (i.e. if the total GFA is 105,000 sqm, each of the Part ST Submission should be about 35,000 sqm)
Common Basement 1 no. of Part ST Submission
Common Podium 1 no. of Part ST Submission
All ancillary works 1 no. of Part ST Submission
All external works 1 no. of Part ST Submission
ERSS Independent submission
*No change from the current arrangement under the standard RABW (without phasing)
Cladding
Façade
Demolition
Temporary Deck

The project team should propose a phasing plan for structural submissions based on this guideline and seek agencies’ concurrence at the pre-submission consultation, before making submissions. 

Phasing of structural submissions at PG is not encouraged. A request can only be put up at the pre-submission consultation for agencies’ consideration* if:

•The site area covers more than 15,000 sqm;
•The project site possession are in multiples phases; or
•The structural design involves complex building;

 

If phasing of structural submission is allowed based on agencies’ assessment:

•The structural submission for PG should generally follow the phasing approach for CG
•When moving on for CG submission, the structural model submitted should be a complete model, including the piling parts cleared at PG

 

*subject to agencies’ assessment and clearance on a case-by-case basis
